Established in 1952 in Tryokhgorny (then known as Zlatoust-36), the Instrumentation Factory was one of the four Soviet sites for nuclear warhead assembly and disassembly. [1] The facility reportedly specialized in installing "physics packages" into ICBM and SLBM warheads. [2]

As a result of consolidation of Rosatom's nuclear weapons activities, the Instrumentation Factory appears to be one of two remaining sites (along with the Elektrokhimpribor Combine) where Russia carries out the assembly and disassembly of its warheads. [3] The facility also manufactures a variety of civilian goods, including nuclear safety and radiation control systems. [4]
